NOTE:Rooting opens up your android and gives you more freedom !! But, when you're sending you TAB to DATAWIND for service or anything like that, you'll have to un-root your TAB (function availbale in Multi-Tool) before sending it.

Pre-requisites :

Since, it cannot be connected to a computer, you need a wifi router with separate IP address for computer and your tablet.(i.e), you need use 'static ip' in your tab to connect to wifi. [Static IP underSettings-->Wireless & Networks-->WiFi Settings-->Advanced.. Note down this IP. Make sure that your TAB is connected to the same router as your computer throughout the process.

Also you, you need any other Android device which can be connected to the computer in USB port via a USB cable, with USB Debugging enabled that device. Just ask your friend to bring his Android Phone/Tablet along with its USB cable and drivers. If you have another Android device with a USB cable for it and all the drivers for it, then use that.
